LIQUID METER.

Application filed August-l9, 1922-. serial' Nd;-583;0I7;'

Be it-known that I, WILLIAM! G. IWALL, a citizen otthe Unitedg States, and aresi-L dent of Indianapolis, county'of' Marion,.. and State of Indiana,-have invented a oer tain new 7 and useful Liq-uid Meter and: I do 'herebydeclare that. the-following is an full-, iclear, and exactdescription thereon reference being had to the-accompanying drawings, in which like" numerals refer :to

i like p art-s.

Thisinvention relates l to 1. a -meter' orv measuringdevice for liquid, and-isparticularly adapted to ineasure liquid wherein the fiow is at an extremely slow'rate, such as is found in measuring-the quantity of gasoline flow to an internal combustion en-i gine'usedfor propelling motor: vehiclesih Liquid meters of the usual is design. are l adaptable only for use 1 inconnection 4 with-:11 liquid having an appreciable :fiow and pres-'1 sure. There. are many ways-in which a measuring meter can be made which will. indicate the quantity 8 of: liquid passing through the device, provided thereis a sufii cient pressure and quantity 1 of fioiwa Thea.

above themham-ber- 10: there are. supporting brackets; 29 and 1:30. The I bracket: 29. :has:

pivoted thereto gat: one endsa vlever r31", saidi.

lever havingxtthe other en'd bi'furcated andi'ri pivotally secured to the upper end of the stem 27 A lever 32 is pivoted at one end to the lever 31 adjacent its connection with the stem 27 and at its other end to the supporting bracket 30. A lever 33 is pivoted at one end to the bracket 30 and is provided with a saddle 34 through which the end of a connecting rod 35 extends, said connecting rod being provided with a nut below and above the saddle 34 so as to limit its movement with respect thereto, and pivotally connected at its lower end to the lever 22 by a pin 37 The saddle 34 is connected to the opposite end of the lever 32 by a spring 36.

Carried upon a suitable bracket 38 mounted on the partition 13, there is a shaft 39 extending horizontally through the housing 14. Rigidly secured upon the inner end of the shaft 39 there is a ratchet wheel 40 and fulcrumed thereon there is a lever 41. One end of the lever 41 is connected to the lever 31 by a' link 42, said link being pivoted substantially midway between the ends of the lever 31. On the opposite end of the lever 41 there is pivotally mounted a pawl 43 in position to engage the teeth of the ratchet wheel 40 for rotating the same. Immediately below said ratchet wheel there is pivotally mounted on the bracket 38 a finger 44 having a weighted end 45 so arranged that it is normally in engagement with the teeth of the ratchet wheel for preventing its reverse movement. The end of the shaft 39 opposite the ratchet wheel 40 is connected with a flexible shaft 46, which may extend, if desired, to the instrument board to be connected with the usual type of register 47.

In operation the asoline enters the measuring chamber 10 through the inlet connection 18, the valve pin 20 being raised so as to permit its flow therethrough. As the level of the liquid raises, it will engage and raise the float 28. As the float 28 is raised, since itis secured upon the stem 27, it will cause said stem to be forced upwardly, thereby carrying upward the end of the lever 31 to which it is pivoted. The upward movement of the lever 31 will force upwardly the link 42 and the end of the lever 41 will carry the pawl 43 down into a new position and en gagement with another toot-h of the ratchet wheel. The same upward movement of the float will raise the lever 32 so as to cause the spring 36 to pass over center and pull up quickly upon the lever 33. The movement of said lever will raise the connecting rod 35 with a quick movement, which will simultaneously lower the valve pin 20, closing the inlet and shutting off the further supply of gasoline, and open the valve 24, permitting the gasoline in the chamber 10 to flow into the chamber 16. As the gasoline flows from the measuring chamber, the float will be lowered by gravity, pulling down the lever 31, link 42 and lever 41 so as to raise the pawl 43 and cause it to turn the ratchet wheel one unit of revolution, which will in turn operate the counter to indicate numerically the quantity of gasoline which has just been received into the chamber and discharged therefrom. The same lowering movement of the stem 27 will pull down on the lever 32, carrying the spring 36 below center, which will snap the lever 33 and connecting rod 35 downwardly, so as to quickly and simultaneously close the opening 25 and lift the pin 20 for permitting a new supply of gasoline to pass into the chamber 10 through the inlet connection 18. The operating capacity of the chamber 10 and the counting elements may be so arranged that the counter will indicate gallons of liquid or fractions thereof.

The meter may be calibrated by adjusting the nuts on the rod 35 so as to obtain any unit of measurement desired within the capacity of the chamber 10.

The invention claimed is:

1. A liquid meter including a casing having a measuring chamber, a float mounted in said chamber, a vertically-extending connecting stem secured to said float at one end, an actuating lever having one end pivotally connected to the other end of said stem, a bracket to which the other end of said actuating lever is pivoted, a rotating shaft hav ing a ratchet wheel mounted on one end thereof, and a second lever pivotally connected at one .end to said first-mentioned lever and provided with a pawl on the other end thereof for engaging and rotating said ratchet wheel upon the vertical movement of said float.

2. A liquid meter including a casing having walls forming a measuring chamber, a float contained in said chamber, a stem secured to said float, a lever pivoted at one end to said stem and at the other end to said casing, a rotating shaft supported in said casing and having a ratchet wheel mounted on one end thereof, a second lever fulcrumed on said shaft, a link connecting one end of said second-mentioned lever with said first-mentioned lever, and a pawl pivotally mounted upon the other end of said secondmentioned lever in position to engage said ratchet wheel for causing the rotation thereof upon the vertical movement of said float.

3. A liquid meter including a casing having walls forming a measuring chamber rovided with inlet and outlet ports, a oat contained in said chamber, a supporting rod vertically secured centrally of said chamber, a hollow stem slidably mounted on said rod to which said float is secured for raising and lowering said stem in accordance with the level of the liquid maintained in said chamber, mechanism connected with the upper end of said stem for registering the movement thereof, an inlet and outlet valve ports,

for said ports, a lever fulcrumed upon the bottom of said chamber connected with said inlet and outlet valves for controlling said and a connecting rod pivoted at one end to said lever and at the other end to said mechanism for controlling said ports upon the operation of said stem.

4. A liquid meter comprising a float-controlled actuating mechanism, said mechanism including a reciprocating stem having a float secured thereon, a casing surrounding said mechanism, a lever pivoted at one end to said stem and at the other end to said casing, a register, a register-actuating shaft pivotally supported in said casing and having a ratchet wheel secured thereon, a lever fulcrumed on said shaft, a linkpivotally connecting one end of said last-mentioned lever with said first-mentioned lever, a pawl pivotally mounted on the opposite end of said second-mentioned lever in position to engage and operate said ratchet wheel in one direction, and a weighted finger pivotally mounted on said casing in position to engage said ratchet wheel for preventing its movement in a reverse direction, whereby the movement of said float when in one direction will cause the rotation of said ratchet'wheel.
